Christopher Columbus left on his first voyage on August 3rd, 1943, on three ships: the Niña, the Pinta, and the Santa Maria. His first stop was the Canary Islands, where he made repairs and stocked up on provisions. He was delayed here for four weeks due to wind, and when he set sail again, wind changed his planned course. On October 7th, the crew spotted shore birds that were flying west, so Columbus changed their course so they could make landfall. Five days later, on October 12th, land was spotted for the first time. Columbus called this land San Salvador. It took about ten weeks for him to reach it from Spain. After landfall, he continued sailing and exploring the nearby islands before beginning his return trip back to Spain. Due to additional storm delays, he didn’t return to Spain until March 15th.

This question refers to the first voyage of Christopher Columbus when he "discovered" America.  The voyage was funded by the Spanish crown in a quest for a western route to India.  Columbus and his crew left Spain on August 3, 1492, from Palos de la Frontera in Spain.  After a stop for repairs and supplies in the Canary Islands, the crew set voyage for the long trek across the Atlantic Ocean.  A sailor by the name of Rodrigo de Triana spotted land in the early morning hours of October 12, 1492.  The land he spotted was in the Bahamas. The indigenous people called the land Guanahani.  From start to finish, the voyage took sixty-seven days or nine weeks and four days.  Columbus would arrive back in Spain on March 15, 1493, making the round trip voyage total 221 days.
